1Safety
The inverter has been designed and tested strictly according to international safety
regulations. Read all safety instructions carefully prior to any work and observe them at
all times when working on or with the inverter.
Incorrect operation or work may cause:
•injury or death to the operator or a third party;
•damage to the inverter and other properties.
All detailed work-related safety warnings and notes will be specified at critical points in
corresponding chapters.
•The safety instructions in this manual cannot cover all the precautions that
should be followed. Perform operations considering actual onsite
conditions.
•SUNGROW shall not be held liable for any damage caused by violation of
the safety instructions in this manual.
1.1 PV Panels
PV strings will produce electrical power when exposed to sunlight and can
cause a lethal voltage and an electric shock.
•Always keep in mind that the inverter is dual power supplied. Electrical
operators must wear proper personal protective equipment: helmet,
insulated footwear, gloves, etc.
•Before touching the DC cables, operator must use a measuring device to
ensure that the cable is voltage-free.
•The opeator must follow all warnings on the PV strings and in its manual.
1.2 Utility Grid
Follow the regulations related to the utility grid.

2
All electrical connections must be in accordance with local and national
standards.
Only with the permission of the local utility grid company, the inverter can be
connected to the utility grid.
1.3 Inverter
Danger to life from electric shocks due to live voltage
•Do not open the enclosure at any time. Unauthorized opening will void
warranty and warranty claims and in most cases terminate the operating
license.
Risk of inverter damage or personal injury.
•Do not disconnect the PV connectors or battery connectors when the
inverter is running.
•Wait at least 10 minutes for the internal capacitors to discharge after the
battery is powered off. Ensure that there is no voltage or current before
disconnecting any connectors.
All safety instructions, warning labels, and nameplate on the inverter:
•Must be clearly legible.
•Should not be removed or covered.
Risk of burns due to hot components!
Do not touch any hot parts (such as the heat sink) during operation. Only the DC
switch can safely be touched at any time.
1 Safety User Manual

3
Only qualified personnel can perform the country setting. Unauthorized
alteration may cause:
•A breach of the type-certificate marking.
•Risk of inverter damage due to electrostatic discharge (ESD)！
By touching the electronic components, you may damage the inverter. For
inverter handling, be sure to:
•avoid any unnecessary touching;
•wear a grounding wristband before touching any connectors.
WWaarrnniinngg LLaabbeell
LLaabbeell DDeessccrriippttiioonn
Disconnect the inverter from all the external power sources
before maintenance!
Do not touch live parts for 10 minutes after disconnection
from the power sources.
Burn danger due to hot surface that may exceed 60 ℃.
Danger to life due to high voltages!
Only qualified personnel can open and maintain the inverter.
Read the user manual before maintenance!
1.4 Batteries
Batteries deliver electric power, resulting in burns or a fire hazard when they are
short circuited, or wrongly installed.
Lethal voltages are present at the battery terminals and cables connecting to
the inverter. Severe injuries or death may occur if the cables and terminals in the
inverter are touched.
Improper settings or maintenance can permanently damage the battery.
Incorrect inverter parameters will lead to the premature aging of battery.

1.5 Skills of Qualified Personnel
All installations must be performed by qualified personnel who should have:
•Training for installation and commissioning of electrical system, as well as dealing
with hazards
•Knowledge of the manual and other related documents
•Knowledge of the local regulations and directives
1 Safety User Manual

2System Solution
The inverter must only be operated with PV strings with class II protection in
accordance with IEC 61730, application class A. It is not allowed for the positive
pole or the negative pole of the PV strings or battery to be grounded. This can
cause the inverter to be destroyed.
Damages to the product due to a faulty or damaged PV installation are not
covered by warranty.
Any use other than the one described in this document is not permitted.
For the TT utility grid, the N line voltage to ground must be 60 V or less.
The three-phase hybrid inverters are applicable to both on-grid and off-grid PV systems.
With the integrated Energy Management System (EMS) , they can control and optimize
the energy flow so as to increase the self-consumption of the system.

ON The inverter is running in the on/off-grid
mode.
Twinkling The inverter is at standby or startup state (-
without on/off-grid operation).
ON
The inverter is running in the mode instead
of on/off-grid mode.
A system fault has occured.
OFF Both the AC and DC sides are powered
down.
2.1.5 DC Switch
The DC switch is used to safely disconnect the DC cirrcuit whenever necessary.
The inverter operates automatically when input and output requirements are met. Rotate
the DC switch to the “OFF” position to stop the inverter when a fault occurs or when
you need to stop the inverter.
Turn the DC switch to the “ON” position before restarting the inverter.
2.2 PV Energy Storage System (PV ESS)
By directly connecting a battery module to the inverter, the conventional PV system can
be upgraded to be an Energy Storage System (ESS).
The system is capable of operating off-grid to ensure an emergency power supply for
protected loads in the event of a grid interruption or blackout, which may be caused by:
•islanding;
•under-voltage or over-voltage;
•under-frequency or over-frequency.
User Manual 2 System Solution

For the TT utility grid, the N line voltage to ground must be 30 V or less.
The utility grid must be a TN system for the off-grid application. Especially when
the utility grid is TN-C system, N line and PE line need to be short circuited
externally when the inverter works as off-grid application.
The system is not suitable for supplying life-sustaining medical devices. It
cannot guarantee backup power in all circumstances.

The battery discharges to provide energy to loads. If the battery is empty or there is not
enough power from the battery system, the grid shall supply the power, first to
emergency loads, then loads.
When the grid is present, the bypass function of the hybrid inverter is actived and the
emergency loads will be directly connected to the grid via the bypass relay integrated in
the inverter.

If the Smart Energy Meter is abnormal or not equipped, the inverter will run normally,
however, the battery can be charged but not allowed to discharge. In this case the feed-
in power setting will be ineffective, and the DO function for optimized mode will be
disabled.
EEnneerrggyy MMaannaaggeemmeenntt dduurriinngg DDaayyttiimmee
The energy management system (EMS) works in self-consumption mode by default.
•Scenario 1: PV power generation ≥ Load power consumption
– First，PV power will go to emergency loads first, then loads and the battery.
– Moreover，If the battery is fully charged, the excess will go to the grid. The feed-
in power will not surpass the feed-in limitation value in initial settings.
•Scenario 2: PV power generation＜Load power consumption
– First，battery will discharge and provide the energy missing.
– Moreover，inverter will draw power from the mains if the power from the PV and
battery is less than the load power.
EEnneerrggyy MMaannaaggeemmeenntt dduurriinngg NNiigghhtt
During night, with energy available, the battery will discharge to supply power for loads.
Alternatively, the grid will supply power for the loads in case the discharge power of the
battery is insufficient.
User Manual 2 System Solution

During night, when the battery is empty, it will enter into standby mode. In this case, the
grid will supply all power for loads.
2.3 Parallel System
Maximum two hybrid inverters with the same type can be connected in parallel in the PV
ESS via RS485 communication. The parallel system can operate in both on-grid and
off-grid modes.
